tailsf-lof "construction.- and arrangement of- I jfigec i ilicatidliof lettersratenfl, I Pafiented"D.ec'.' 13,5[9101' Serial No 492,437"- 'lheidevieeconsists essentially a base frame which -1S substantially rectangular in contour havin side sills.5,a nd i-the opposite ends of whici are'f'connected by the end pieces 7 and 8'. In thepresent construction this frame is such that it may be drawn Shy the draft animals over-the field or it may be. provided with wheels when the ound and other circumstances demand. I shaft .or

trunnion 9 has itsopposite ends" secured in the opposite side sills 5 aud t at sub-- stantially their intermediate portion, this shaft or trunnion 9 forms apivotal support for the hoisting beam. The latter in the present instance is substantiallyi'a ll-shaped 1 structure and. comprises the side sections I 10 and 11. Each of these sections are substan- 'tially V shape in contour andadjace'nt their pointed ends connected bye cross; beam 12.

lhe length of the cross beam'is somewhat less than the distance b'etween the sins-5 and (3, so that when the parts are in position as shown in the drawings the distance between the pointed ends and hoisting beams-Will be. sirbstant-ially the same as the distance be tween the side sills 5 and 6. 'Ehekpointed end portions are provided with al-in i'ng openings for-the reception of-the shaft-or trun nion 9, thus it'Wlll be seen that the hoisting I beam may be oscillated on-the-sh'aft and the limbs-13 and'l alternately raised and-debrace rod '16 or other suitable means.

- pressed. The free ends 'o-fthelimbs and 14 are brought together and rigidly secured The stacker structure's consistof elongated arms-17, slnce each of-these stackers are identical in structure a description of one will be sufficient for both. As beforestated;

I each structure consists" of an arm 17, the

lower end of which terminates a pin- By referring now to the drawin s it w ll be seen that the medial orti'on o thfecress beam. 12 is provided wit 1' atransVrse strip 1-9 the opposite ends of Which extend 1 beyond the opposite longitudinal-sides of the cross beam 12 andare turnedslightlydowh- Ward and provided withopenings for'.,th e loose reception of. the pins lB-at the lower -ends of the armsasclearly shown in the .drawings- Thus ,it-will be seen that the stacker arm's are 'swiveled to the hoistingbeam.-,.-The upper or-"oppo'site'terminal 0 each of the beams '17 is provided with a transverse joist 20' the opposite ends of I which extend equal distances beyond the opposite sides of the arm.

' the body portion 22 mediate portion 32 are connected to ends anchored This 1oist forms a support for the fork 21. The latter may be of any well known structure and in the present instance is shown to consist of a transverse body portion 22 from the front side of which extends the prongs 23, the opposite end prongs extend rearwardly and eyond ands-are provided with suitable counterweights 2st, the function of which is to maintain the fork in a substantially horizontal plane. Extending upwardly from the extreme upper end of the arm 17 is an'upright 25 which is provided with a longitudinal opening in which is pivoted the intermediate portion of a keeper 26, and extending upwardly from the medial portion of the body 22 is a tongue 27 the free end of which is adapted; to be engaged by the keeper when the latter is in its normal horizontal posit-ion. ,By'referring now to the drawin 's it will be seen that the upper faces of eac 1 of thearms 17 is provided with a leaf spring 28 the free end of which bears on the lower edge of the keeper 26 and forces the same upwardly whereby its outer or engaging end is yieldingly held in' position to engage the tongue 2-7.

Connection between the fork mechanism and means 'of aguy wire or cable 29 the interof which 'is suitably secured to-the upper ends of the limbs and the free or otherwise secured. to the opposite ends of the oist 20. A suitable trip cord 30 has one en secured to the-outermost end of the keeper 26 from which it is led over the top of the upright 25 and thence downwardly and through an eye or pulley on the upper end of either of the sills 5 or 6. Operating cords or cables 32 have their upper ends secured to the upper ends of the limbs 13 and 14 and their ends reeved through pulleys 33 and 34: secured to 'the' and the operating elementsthe draft animals so that when one fork is lowered and loaded with hay one of the draft animals is driven forward and the other backed which will resultin the lowered fork rising to dumping position and the opposite fork being depressed or lowered to loading position. \Vhen the first-named fork is 'in dumping end pieces? and 8 and the side sills 5 6. The free ends of position, by means of the tripping cord'30 the keeper will be disengaged from the tongue26 and the fork will ravitate to dumping position by virtue o? the excess weight on the prongs.

Thus it will be seen that I have provided a structure whichis comparatively simple to perform its'dumping function'in a rapid and effective manner.

the limbs 13 and 14 is established by The swiveled connection between the ears 17 and one of the cross beams 12 will permit the forks to dump on either side of the frame, whereby without changing the position of thedevice.

Having thus described my invention, what is claimed as new, is

l. A stacker comprising a beam mounted for oscillation in a vertical plane and forks each having an arm connected at its lower end to the said beam for angular movement and also for turning movement, said arms being disposed at opposite sides of the said beam so that when one fork is raised the other is lowered.

2. A stacker comprising a beam mounted for oscillation in a vertical lane, arms on opposite sides of said beaman the plane of movement thereof and mounted for angular movement with respect to the beam and also for turning movement, forks carried-by the respective arms and connections between the said arms and the said beam whereby when one of said arms is raised by the beam the other is lowered.

3. A stacker comprising a beam mounted for'oscillation. in a vertical plane, arms on opposite sides of'said beam in the plane of movement thereof and each having its lower end swivelly connected thereto so that said arms are movable angularly with respect to said beam andare also enabled to be turned,

forks at the upper ends of and carried by the said arms, flexible connections bet-ween said forks and said beam and means for operating the latter so that when the beam is moved in either direction one of said'arms with itsfork is raised and the other is lowered.

L A stacker comprising a base frame a substantially 'V-shaped beam pivotally connected at its lower end to said base frame and movable angularly in a vertical plane,

g means for operating said beam, arms having their lower ends swivelly connected to opposite sides of said beam in the plane of two stacks may be formed movement thereof, forks carried by the said arms flexible connections between said forks and the said beam and means said forks.

5. A stacker for angular movement in a vertical plane, arms also mounted for movement angularly in a vertical plane and disposed on opposite sides of said beam in the plane of movement thereof,- means for operating said beam, forks carried bythe said arms, each of said forks having a head rigidly fixed to said arm and a tine member pivotally connected to said head, flexible connections between the fork heads and the beam locking means to secure the tinemembers of the forks to the heads thereof in loading position andzmeans to operate said locking means to cause Said forks to discharge their loads.
